[PATCH] powerpc: Expose SMT and L1 icache snoop userland features

2006-03-03T11:00:23+00:00

This patch makes userland aware of the icache snoop capability of the
POWER5 (and possibly others in the future) and of SMT capabilities.

[PATCH] powerpc: Enable coherency for all pages on 83xx to fix PCI data corruption

2006-02-24T00:36:25+00:00

On the 83xx platform to ensure the PCI inbound memory is handled properly we
have to turn on coherency for all pages in the MMU.  Otherwise we see
corruption if inbound "prefetching/streaming" is enabled on the PCI controller.

[PATCH] powerpc: oprofile cpu type names clash with other code

2006-01-14T00:12:16+00:00

In 2.6.15-git6 a change was commited in the oprofile support in
the powerpc architecture.  It introduced the powerpc_oprofile_type
which contains the define G4.  This causes a name clash with the
existing wacom usb tablet driver.

      CC [M]  drivers/usb/input/wacom.o
    drivers/usb/input/wacom.c:98: error: conflicting types for `G4'
    include/asm/cputable.h:37: error: previous declaration of `G4'
      CC [M]  drivers/usb/mon/mon_text.o
    make[3]: *** [drivers/usb/input/wacom.o] Error 1
    make[2]: *** [drivers/usb/input] Error 2

The elements of an enum declared in global scope are effectivly
global identifiers themselves.  As such we need to ensure the names
are unique.  This patch updates the later oprofile support to use
unique names.

powerpc: Provide a suitable AT_PLATFORM value

2006-01-13T23:11:39+00:00

The glibc folks want to use AT_PLATFORM to select between possible
alternative versions of shared libraries.  This commit makes the kernel
supply an AT_PLATFORM string that indicates what class of processor
we are running on.  Processors with the same set of user-level
instructions and roughly the same instruction scheduling characteristics
are given the same AT_PLATFORM value; for example, 821, 823 and 860
are all reported as "ppc823", and 7447, 7447A, 7448, 7450, 7451, 7455
are all called "ppc7450".

The intention is that the AT_PLATFORM values match the values that
gcc accepts for the -mcpu= option.  For values which are numeric
(e.g. -mcpu=750), "ppc" has been prepended.

This also adds a PPC_FEATURE_BOOKE bit to the AT_HWCAP value and sets
it for the 440 family and the Freescale 85xx family.

[PATCH] ppc64: Fix oprofile when compiled as a module

2006-01-09T05:02:52+00:00

My recent changes to oprofile broke it when built as a module. Fix it by
using an enum instead of a function pointer. This way we still retain
the oprofile configuration in the cputable.

[PATCH] cell: enable pause(0) in cpu_idle

2006-01-09T04:44:32+00:00

This patch enables support for pause(0) power management state
for the Cell Broadband Processor, which is import for power efficient
operation. The pervasive infrastructure will in the future enable
us to introduce more functionality specific to the Cell's
pervasive unit.

[PATCH] powerpc: sanitize header files for user space includes

2006-01-09T04:13:08+00:00

include/asm-ppc/ had #ifdef __KERNEL__ in all header files that
are not meant for use by user space, include/asm-powerpc does
not have this yet.

This patch gets us a lot closer there. There are a few cases
where I was not sure, so I left them out. I have verified
that no CONFIG_* symbols are used outside of __KERNEL__
any more and that there are no obvious compile errors when
including any of the headers in user space libraries.

[PATCH] powerpc: Dont set 32bit cputable bits on 64bit

2006-01-09T03:53:41+00:00

Milton and I were looking at the cputable code and it looks like we can
set spurious bits on 64bit.

[PATCH] powerpc: merge align.c

2005-11-18T03:39:23+00:00

This patch merges align.c, the result isn't quite what was in ppc64 nor
what was in ppc32 :) It should implement all the functionalities of both
though. Kumar, since you played with that in the past, I suppose you
have some test cases for verifying that it works properly before I dig
out the 601 machine ? :)

Since it's likely that I won't be able to test all scenario, code
inspection is much welcome.

powerpc: Add user CPU features for POWER4, POWER5, POWER5+ and Cell.

2005-11-10T03:29:18+00:00

This is at the request of the glibc folks, who want to use these bits
to select libraries optimized for the microarchitecture and new
instructions in these processors.
